Well, I was just about to publish my first library to npm but just changed my mind. I have enough performance anxiety as it is and when I know people think I'm destroying the scene with my "sub-par code" I definitely won't publish.
There's a worst case of no-one noticing, which will hopefully be a great relief for the anxiety (and yet you can say you published your code), and a next worst case that it's never used and is simply inspiration for a better library! Of course best case is people use your code, modify, expand, and build upon it. You'll be credited in their libraries as part of their inspiration, and the state of the art moves forward.
There are many that want deeper curation on quality; it's hard to deal with all the noise out there. But it's critical to remember that we can always layer curation on top of the bazaar at no additional cost. As the scene settles into its grooves, the better curators will stand out.
